CREAM-TESTING' CHURN.

SPECIFICATION forming part of Letters Patent No. 346,051, dated July 20,1886.

Application filed November 16, 1885. Serial No. 183,016. (No model.)

v To all whom it may concern:

Be it known that I, JOHN F. Korir, of Chicago, in the county of Cook andState of Illinois, have invented certain new' and useful Improvements ina Cream-Testing Churn, of which the following is a full, clear, andexact description, that will enable others to make and use the same,reference being had to the accompanying drawings, forming a part of thisspecification.

This invention relates to an apparatus de signed to churn and testsamples of cream taken from different lots; and it consists of certainnovel features in the construction and combination of parts, as will behereinafter set forth.

Figure l is a vertical transverse section of an apparatus embodying myimproved features; Fig. 2, a side elevation and partial scction; Fig. 3,a view in'perspective of a removable case adapted to hold thetest-tubes. Figs. 4, 5, 6, and 7 are detached details.

Referring to the drawings, A represents the supporting-frame, which maybe of any desired form or design.

Thereciprocating box or receptacle B will lze ordinarily constructed ofcast-iron; but

any other material suitable for the purpose may be used. This lorms thechurn boX proper, and the required reciprocating movement is imparted tothe same through the medium of the angular connectingrod Band thedouble-crank shaft B2, which is provided with suitable journal-bearingsin the supporting-frame. B is a balance-wheel mounted on one end ot'said shaft, and Bl a drivingpulley mounted on the opposite end, asillustrated in Fig. 2. One end of the-angular rod B is connected to thelug a on one side of the churnboX, and the opposite end to thedouble-crank shaft.

The ends oi the churn-box are provided f with the oscillating bearingsa'c, as shown in Fig. 2.

The removable test-case C consists of a frame-work of wire and the endsa? at. This case is open on the sides, (see Fig. 3,) and is adapted tobe placed on the inside of the churn-box, as shown in Fig. l.

zontally inthe perforated parts.

c5 is an adjustable diaphragm supported on the top and bottom wires ofthe case C, and nearer to one end than to the other, as shown in Figs. land 8. This diaphragm is provided with the numerous perforations a,while the end c4 ot' the case is provided with correspondingperforations, a7. The series of glass testtubes D are inserted andsupported horitSee Figs. 1 and 3.)

There is space left between the inclosing sides of the churn-box and thecase C, so that when the latter is placed in position the stoppers b,inserted in the open iiaring ends of the test-tubes, bear against oneside of the churnboX, (see Figs. l and 7,) while the opposite ends ofsaid tubes bear against the imperforated end a3 of the case.

D is an adjustable swiveled clamping-plate, the inner side of whichbears against the outer side of the end c of the case C. The outer sideof the plate D' is provided with the internallythreaded hub b', as shownin Figs. 5 and 7. i

DL is an adjusting screw-bolt having a threaded connection with the hubb ou the plate D'. (See Fig. 5.) The box lug b? is formed on the outsideof the churn-box, and provides a bearing for the screw D2. This boxlugis open on the top, as shown in Fig. 4, so

as to conveniently permit of the removal of 8o said screw from the hubbyraising these parts upwardly in the elongated slot b3. The collar b" andthe rigid head b5 prevent an endwise movement ofksaid screw bolt, theclampingplate moving in or out as the screw is rotated. The function ofthis clamping plate is to lightly clamp the test-tubes in place whenbrought to a bearing against the imperforated end of the case C, whichwill spring suficiently for the purpose. This arrangement not onlysecures the test-tubes, but also prevents all possibility of the stopperescaping from the same.

One or more testcases may be used in the same receptacle, as shown bythe broken-away part, Fig. 2, for the purpose of facilitating thehandling of the same, a separate clampingplate being used for each1case. The handle time, through the Waste-valve d.

b provides means for lifting the case out of the receptacle, and thecover 67 tightly closes the same.

The heating and warming reservior or chamber D3 is located underneaththe churn-box, and is supplied with steam or hot Water through theconnection d, the Water being discharged, as may be required from timeto v The temperature in the churn-boX may be reduced by removing thecover and letting in ajet of cold Water, which will escape through thetube D", (see Figs. 1 and 6,) inserted in the center of theWarming-reservoir and secured in place by the screW-nutsd2 al, andatight joint formed al; each end by the interposed packing-rings (Z d5.

In practical Working the test-tubes first receive a sample of cream fromeach lot, there being as many tubes used as there are different lots tobe tested. The tubes are next placed in the churn-box, and the samewarmed to the proper temperature, and then ehurned, after which thetemperature is increased sufficiently to separate the oil ofbutter fromthe curd and Whey, when the exact quantity of oil in each tube or sampleis accurately known. This arrangement requires but a small sample fromeach lot of cream, and the process of testing the same is easily andquickly performed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination, with the oscillating churn-body, of a removable casehaving one perforated and one mperforated end, and provided between saidends With an adjustable perforated diaphragm, and means, substantiallyas described, forclamping the case in said churn-body, for the purposeset forth.

2. The combination of a churn body, mechanism for oscillating the same,a removable case in said body, and having a number of test-tubes, and aclamping device which clamps said tubes and case against the Walls ofthe churnbody, substantially as described.

8. In a testchnrn. the combination, with a removable tube-holding case,of a clampingplate provided on one side with' an nteriorlythreaded huband a swiveling screw-bolt provided with the collar b4, and the rigidhead b5, and adapted to engage with said hub, whereby said clampingplatemay be adjusted as required, substantially as and for the purpose setforth.

4. A test-churn consisting of a box receptacle adapted to have anoscillating movement, a removable case. as described, a number oftest-tubes inserted in said case, and a device for clamping said caseand tubes against the body of the churn. and a heating reservoir orchamber located below said receptacle, Whereby the test-tubes are heatedto the required temperature, substantially as and for the purpose setforth.
